Embodiment 1

[0020] At a room temperature of 25° C., in parts by weight, the shaping paste is composed of: 2 parts of rosin, 3 parts of high-speed engine oil, and 5 parts of talc.

[0021] The preparation method of the above-mentioned shaping paste is: take 2 parts by weight of rosin into a stainless steel pot, heat it to 160℃, then add 2.5 parts by weight of talcum powder, and stir at 160℃ for 5 minutes; then add 2 parts by weight And stir at 160℃ for 5 minutes; then add 1.25 parts by weight of talc and stir at 160℃ for 5 minutes; then add 1 part by weight of high-speed oil and stir at 160℃ for 5 minutes; finally Add 1.25 parts by weight of talc, and stir at 160° C. for 10 minutes to obtain a mixed liquid, and then cool the mixed liquid to obtain a shaping paste.

Embodiment 2

[0023] At a room temperature of 10° C., and in parts by weight, the shaping paste is composed of 4 parts of rosin, 2 parts of high-speed engine oil, and 4 parts of talc.

[0024] The preparation method of the above styling paste is: take 4 parts by weight of rosin into a stainless steel pot, heat it to 170°C, then add 2 parts by weight of talcum powder, and stir at 170°C for 5 minutes; then add 1.3 parts by weight And stir at 170°C for 5 minutes; then add 1 part by weight of talc and stir at 170°C for 5 minutes; then add 0.7 part by weight of high-speed oil and stir at 170°C for 5 minutes; finally Add 1 part by weight of talcum powder and stir at 170° C. for 10 minutes to obtain a mixed liquid, and then cool the mixed liquid to obtain a shaping paste.

Embodiment 3

[0026] At a room temperature of 35° C., and in parts by weight, the shaping paste is composed of: 3 parts of rosin, 3 parts of high-speed engine oil, and 4 parts of talc.

[0027] The preparation method of the above-mentioned shaping paste is as follows: take 3 parts by weight of rosin into a stainless steel pot, heat it to 160°C with electric heating, then add 2 parts by weight of talc, and stir at 160°C for 5 minutes; then add 2 parts by weight Then add 1 part by weight of talcum powder and stir at 160°C for 5 minutes; then add 1 part by weight of high-speed motor oil and stir at 160°C for 5 minutes; finally Add 1 part by weight of talcum powder and stir at 160° C. for 10 minutes to obtain a mixed liquid, and then cool the mixed liquid to obtain a shaping paste.

Abstract

The invention relates to a shaping paste used for manual forging forming of metal sheets and a preparation method of paste, and relates to the field of solid deformation materials. The preparation method of the shaping paste comprises: taking 2-4 parts by weight of rosin, 2-4 parts by weight of high-speed engine oil and 3-5 parts of talcum powder for usage; putting all taken rosin into a stainless steel heating pot, heating to 150-170 DEC G by utilizing electricity; then alternately adding readied talcum powder and high-speed engine oil in parts into the heating pot with stirring until the readied raw materials are all added; and cooling the mixed solution in the heating pot, so as to obtain the shaping paste. When the indoor temperature is less than 10 DEG C, dibutyl ester and dioctyl ester, which account for less than 8% by weight of the sum of rosin, high-speed engine oil and talcum powder, are sprayed on the surface of the cooled shaping paste. The shaping paste disclosed by the invention has good plasticity, and is capable of effectively improving the precision degree of manual forging forming of the metal sheets.

Description

Technical field [0001] The invention relates to the field of solid deformable materials, in particular to a shaping paste used for manual forging and shaping of metal plates and a preparation method thereof. Background technique [0002] The technique of forging copper relief is to use a hammer and a chisel to forge a relief-like pattern of ups and downs on the surface of the copper plate with a hammer and chisel, and finally make exquisite crafts. During the forging and engraving process of the copper plate, supporting material is required under the copper plate. The traditional process uses sandbags, but the sandbags cannot be tightly combined with the copper plate. During the forging and forming process of the copper plate, the sandbag is filled with too much sand. Too many sandbags may be insufficiently deformed with the copper plate, while too little sand filling can not accurately deform with the copper plate, thus affecting the forming accuracy of the copper plate.
